The light was delivered in a reasonable amoun tof time and was packaged safely.The brightness is somewhat adjustable from dim to its brightest via a touch panel on the light's base. That toush panel as well as all the other controls, is not an array of protruding switches, but a capacitive toush system. There's a touch location for On/OFF, for a few different automatic OFF settings and one to change the light from flourescent to incandescent modes. There's more than one different shades of the incandescent look.The light looks nice and the stand holds the light in place well. The light swivels and adjusts in 3 directions while the stand can remain in the place where set by the user.I bought the light to put where I tie fly baits. It helps me see better. There's times I think I want the light to be a little brighter, but my eyes don't work as well some days as they work on other days. Oh well.The timer mode sometimes catches me by surprise because it turns the light off automatically after an amount of time dependent on how the timer is set. I can't designate which exact button pushes control the different functions, but that's likely detailed in the instructions. I only read enough of the instructions to get the light on and off.The light runs via a USB wall wart. There's no internal battery that I can tell. There's 2 USB receptacles on the back of the base. I'm running the light with the USB C connector plugged into the base. The other USB receptacle is USB A.So far I'm happy with the light. If I see the need I'd buy an additional one - or - more.
